#### Steps:

1. Call the bundle/register endpoint with the following request body:

* seed: the seed of the account that will pay for the transaction.
* class\_id: the new class identifier that the bundle will manage.
* asset\_id: the new asset identifier that the bundle will manage.
* schema: this will represent all the classes and assets that need to be present in order to fulfill the other transactions 
  * class\_ids: an array of the class identifiers that will be part of the schema.
  * asset\_ids: an array of asset\_ids arrays that will be related to each class\_id.
  * amounts:  an array of amount arrays that will be related to each asset\_id.
* metadata: additional information about the bundle.

#### Example Input:

```
{
    "seed": "//Alice",
    "class_id": 3,
    "asset_id": 0,
    "schema": {
        "class_ids": [1],
        "asset_ids": [
            [1]
